Organic Derivatives of Mica‐type Layer‐Silicates

Mica‐type layer‐silicates such as montmorillonite and vermiculite are capable of exchanging their cations for other (including organic) cations, just like the zeolites. These derivatives swell in a variety of liquids. This paper presents a survey of the structures of organic derivatives of mica‐type layer‐silicates and illustrates some possibilities for their industrial utilization.
